[SIPForum-discussion] In case of Parallel forking how an incoming responses from different branches are identified at proxy

[Hemant Kumar]

The branch parameter in Via must be different for the every forked call leg
as that is used by the forking proxy to identify which leg has responded.
So in the example given by *HM Kias*, the branch parameter in the 180
responses should be different if the proxy is forking in parallel.

Regards,
Hemant
